4-formyl-benzamido-dPEG®₂₄-TFP ester

4-formyl-benzamido-dPEG®24-TFP ester, product number 10082, is an aryl aldehyde partner for our hydrazide- and aminooxy-containing products. This product introduces an aldehyde into a peptide, protein, or other biomolecules by reacting the 2,3,5,6-tetrafluorophenyl (TFP) ester end with free amines. Reaction with a molecule containing a hydrazide or aminooxy reactive group forms hydrazone or oxime bonds.

PEGylation with 4-formyl-benzamido-dPEG®24-TFP ester
OurdPEG® technology creates single molecular weight PEG products with discrete chain lengths. In contrast, traditional PEG reagents are dispersed polymers containing an intractable mixture of different chain lengths of PEG, each chain having a different molecular weight. This dispersity creates significant analytical challenges for users of conventional PEG products. Our dPEG® products provide all of the benefits of traditional PEG products without the accompanying analytical complexity found in dispersed PEG polymers.
